THE COMPUTATION OF THE MOMENTUM AND HEAT FLUXES DUE TO STATIONARY PLANETARY WAVES RESPONDING TO FORCING BY THE NORTHERN HEMISPHERIC TOPOGRAPHY AND STATIONARY HEAT SOURCES IN WINTER

The stationary planetary wanes responding to forcing by the northern hemispheric topography and stationary heat souces in winter are investigated by means of a quasi-geostrophic, steady state, 34-level model, with Rayleigh friction, the effect of Newtonian cooling and the horizontal kinematic thermal diffusivity included in a spherical coordinate system. The momentum and heat fluxes due to stationary planetary waves responding to forcing are computed, and are qualitatively in good agreement with the observed results. The computed results show that the poleward momentum and heat flux in the stratosphere has a maximum, respectively.
